Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, for example, to a centrifuge basket. Background Art

[0002] At present, the centrifuge will generate strong centrifugal force due to the high-speed rotation of the rotor during normal centrifugal operation. When the centrifuge tube (bottle) breaks or the centrifuge tube (bottle) seal fails, aerosols or biological samples carrying bacteria, viruses, etc. will splash out, causing pollution to the entire centrifuge chamber and laboratory, and causing harm to the centrifuge operator or experimenter. Therefore, it is necessary to permanently close the airtightness of the basket body during the centrifugation process. Laboratory biosafety requires a complete set of protective measures and means to prevent the inadvertent exposure and release of pathogens or toxins. As an important part of biosafety protection, the centrifuge basket sealing cover can effectively prevent the leakage of harmful samples during the centrifugation process and protect the laboratory environment and personal safety.

[0003] The related art discloses a biosafety sealing cover structure on a centrifuge, comprising a hanging basket and a cover body matched with the hanging basket; the hanging basket is provided with an upper port as a sealing surface, and bosses are provided on both sides; a rotatable inverted U-shaped handle is provided on both sides of the cover body, and a sealing ring matched with the upper port of the hanging basket is provided on the lower port; locking grooves that can be matched with the bosses on the hanging basket are provided at both ends of the handle. The utility model has a simple structure and is easy to use. The handle is matched with the boss on the hanging basket through the locking groove. The cover body and the hanging basket can be sealed by rotating the handle with one hand. Compared with the traditional screw cap and buckle-type biosafety sealing cover, the sealing can achieve a more effective protective effect.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Both ends of the cover in the related art are snap-on structures, so each time the cover is opened, the cover needs to be removed and placed elsewhere, which easily causes contact contamination.

[0074] Optionally, the upper surface of the unlocking arm 203 is a plane, which is also convenient for the user to place his fingers and apply force to press.

[0075] Alternatively, if Fig. 9 and Fig.10 As shown, the hole wall of the rotating hole 205 is constructed with a first limit block 2051, and the rotating shaft 206 is constructed with a second limit block 2061. When the rotating shaft 206 is located in the rotating hole 205, the second limit block 2061 is located on the side of the first limit block 2051 away from the cover body 20, and the first limit block 2051 is in contact with the second limit block 2061 to limit the rotating shaft 206 from escaping from the rotating hole 205.

[0076] In the disclosed embodiment, when the rotating shaft 206 is located in the rotating hole 205, the second limit block 2061 constructed by the rotating shaft 206 can be close to (fit with or approach) the outer side of the first limit block 2051 to limit the rotating shaft 206 from detaching from the rotating hole 205, thereby further improving the connection stability between the rotating switch 201 and the cover body 20.

[0077] Alternatively, if Figure 1 and Figure 2 As shown, the centrifuge basket also includes a limiting protrusion 207, which is arranged at the first end of the cover body 20; wherein, the rotary switch 201 rotates from the first position to the second position along the second direction, and when the rotary switch 201 rotates to the first position, the rotary switch 201 abuts against the limiting protrusion 207, which is used to limit the rotary switch 201 from rotating freely along the second direction.

[0078] In the disclosed embodiment, the first end of the cover body 20 is further provided with a limiting protrusion 207, so that when the rotary switch 201 is rotated to the first position, the limiting protrusion 207 can limit the rotary switch 201 from rotating in the second direction, so that the rotary switch 201 can be prevented from freely rotating in the second direction, and free rotation means that the rotary switch 201 rotates from the first direction to the second direction without the action of a large external force. It can be understood that the limiting protrusion 207 can limit the free rotation of the rotary switch 201, but under the action of an external force, the rotary switch 201 can break through the limit of the limiting protrusion 207 and rotate toward the second position.

[0079] Optionally, the limiting protrusion 207 protrudes from the outer wall surface of the cover body 20 , and the protruding distance is less than the preset distance, which can not only play a limiting role in preventing free rotation, but also facilitate the user to control the rotary switch 201 to break through the limiting role of the limiting protrusion 207 .

[0080] Optionally, the distance that the limiting protrusion 207 protrudes from the outer wall surface of the cover body 20 is less than 1 mm, for example, it can be 0.1 mm, 0.2 mm, 0.5 mm, 0.6 mm or 0.8 mm.

[0081] Optionally, when the rotary switch 201 is rotated to the first position, the limiting protrusion 207 is located above the unlocking arm 203 , and the limiting protrusion 207 can limit the unlocking arm 203 from rotating in the direction of the locking arm 204 .

[0082] Optionally, the outer wall surface portion of the first end of the cover body 20 is recessed inward to form a groove, the rotating shaft 206 is disposed in the groove, and the rotary switch 201 is rotated and located in the groove. This can reduce the protruding size of the rotary switch 201, thereby reducing the size of the centrifuge basket, improving the compactness of the centrifuge basket installation, and avoiding interference with other components.

[0083] Alternatively, if Fig.10 As shown, the rotary switch 201 protrudes toward the wall portion of the hanging basket body 10 to form a first step 208; the cover body 20 includes a cover body 20 main body and a second step 209, and the second step 209 is arranged on the outer wall surface of the cover body 20 main body and protrudes from the outer wall surface of the cover body 20 main body; wherein, when the rotary switch 201 rotates from the second position to the first position along the first direction, the first step 208 abuts against the second step 209 to limit the rotary switch 201 from continuing to rotate along the first direction.

[0084] In the embodiment of the present disclosure, the first step 208 and the second step 209 are in contact with each other, which can limit the rotary switch 201 from rotating too far and prevent the locking groove 202 and the locking protrusion 101 from separating again.

[0085] Alternatively, if Figure 6 and Figure 7As shown, the centrifuge basket also includes a rotating protrusion 102 and a rotating shaft 30. The rotating protrusion 102 is arranged at the second end of the basket body 10, that is, the other side of the opening. The rotating protrusion 102 is configured with a rotating hole 103, and a notch 1031 is opened on one side of the rotating hole 103; the rotating shaft 30 is connected to the second end of the cover body 20, and the rotating shaft 30 is rotatably and detachably located in the rotating hole 103; wherein, when the cover body 20 is opened and rotated to a preset angle, the rotating shaft 30 can be detached from the rotating hole 103.

[0086] In the disclosed embodiment, the second end of the hanging basket body 10 is provided with a rotating protrusion 102, and the rotating protrusion 102 is provided with a rotating hole 103. The second end of the cover body 20 is provided with a rotating shaft 30, and the rotating shaft 30 is rotated and located in the rotating hole 103, so that when the first end of the cover body 20 is opened, the cover body 20 can rotate around the rotating shaft 30 at the other end thereof, which is convenient for the user to open the cover with one hand, and the cover body 20 does not need to be removed, and there is no need to find another place to place the cover body 20. In addition, a notch 1031 is provided on one side of the rotating hole 103, so that when the cover body 20 needs to be removed, the cover body 20 is rotated to a preset angle, and the rotating shaft 30 can be separated from the rotating hole 103 from the notch 1031, thereby separating the second end of the cover body 20 from the other end of the hanging basket body 10, so that the cover body 20 can be separated from the hanging basket body 10, so that it is convenient for the user to perform other operations on the hanging basket body 10.

[0087] Optionally, the notch 1031 is located above the rotating hole 103, so that when the cover 20 is rotated 90°, the cover 20 is pulled upward to remove the rotating shaft 30 from the notch 1031, which can ensure that the cover 20 has a large rotation angle when opened and completely avoid the opening, making it easy to take and put items. At the same time, it can also avoid turning the cover 20 to a large angle to remove it, which will occupy extra space outside the centrifuge basket and make it inconvenient to disassemble.

[0088] Optionally, the notch 1031 may also be located on the left or right side of the rotating hole 103. The notch 1031 is located on the right side of the rotating hole 103, that is, when the notch 1031 is located on the side of the rotating hole 103 facing away from the opening, the rotating shaft 30 can be disassembled when the preset angle is greater than 90 degrees. The notch 1031 is located on the left side of the rotating hole 103, that is, when the notch 1031 is located on the side of the rotating hole 103 facing the opening, the rotating shaft 30 can be disassembled when the preset angle is less than 90 degrees. In practical applications, the position of the notch 1031 can be set according to requirements.

[0089] Optionally, the second end of the cover body and the hanging basket body can also be rotatably and detachably connected in other ways, such as using a magnetic coupler or a coupling to connect the two rotating shafts to achieve rotation and detachable connection. These are all existing technologies and will not be described in detail in this application.

[0090] Optionally, the first end of the cover 20 is arranged opposite to the second end of the cover 20, so that when the cover 20 needs to be locked, the cover 20 is first rotated downward to cover the opening of the hanging basket body 10, and then the locking arm 204 of the rotary switch 201 is pressed to make the locking groove 202 of the rotary switch 201 match the locking protrusion 101, so that not only the first end of the cover 20 is connected to the hanging basket body 10, but also the second end of the cover 20 and the second end of the hanging basket body 10 can be further pressed under the locking action of one end of the cover 20, thereby improving the sealing of the cover. When the cover 20 needs to be disassembled, the unlocking arm 203 is pressed, the notch 2021 of the locking groove 202 corresponds to the locking protrusion 101, and the locking groove 202 is separated from the locking protrusion 101, so that the first end of the cover 20 is separated from the first end of the hanging basket body 10, and the cover 20 can be rotated to open the opening, and the user can take and put items in the hanging basket body 10. When the cover 20 needs to be removed, the cover 20 can be further rotated to a preset angle, and then the rotating shaft 30 can be removed from the notch 1031 by pulling the cover 20, thereby separating the cover 20 from the hanging basket body 10.

[0091] Optionally, the centrifuge is provided with a horizontal rotor 40, and the centrifuge basket is installed on the horizontal rotor 40. After the centrifuge tube containing biological samples or aerosols is placed in the basket body 10 and the cover body 20 is sealed and connected, the centrifuge basket will be swung from a vertical position to a horizontal position to facilitate centrifugation of the sample in the centrifuge tube.
